About two weeks ago I was referred to an oral surgeon for wisdom teeth extraction. All four teeth are impacted and need to be extracted, and it is quite painful. After they took the X-Rays, they told me what procedures I needed to have done. They told me I'd need to have the teeth extracted, and that I'd need a bone graft for each tooth that was removed, and that the bone graft was $350 a tooth. I also needed a membrane (not sure if that's the exact name of the procedure, but thats what they told me) for each tooth that was removed, which was $850 a tooth. They told me that my insurance would not cover the bone graft and membrane, so I'd have to pay for that myself. I asked why I needed a bone graft and membrane for each tooth, they told me that the bone graft was to prevent bone loss, and the membrane is so I won't have sinus trouble. They told me that 80% of oral surgeons don't do this procedure, and they insist on me getting it done. I am very skeptical, and I would like an opinion on this.
